The Siemens SENTRON 5SL4110-6CC is a 1-pole miniature circuit breaker with a B tripping characteristic, rated 10 A and a breaking capacity of 10 kA according to EN 60898. That 10 kA at 230/400 V AC means it can safely interrupt a fault current up to 10,000 amps without welding its contacts or letting an arc escape — critical for residential and light commercial panels where the prospective short-circuit current at the service entrance can hit that level. The B-curve (3–5× In) trips fast on moderate overloads, which suits resistive and general-purpose loads like lighting, receptacles, and control transformers; it's not meant for motor starting where a C or D curve would be needed to ride through inrush.
Where it goes and what it connects to
Rated for residential buildings and infrastructure, the 5SL4110-6CC lives in DIN-rail distribution boards protecting branch circuits. The IP20 rating (finger-safe only with conductors connected) means it belongs inside a closed enclosure — not in a washdown area or outdoors without a weatherproof cabinet. The breaker accepts supplementary devices like auxiliary switches, shunt trips, or alarm contacts — useful for remote status or emergency-off integration. It's sealable, which lets a utility or inspector lock the handle position. Halogen-free and silicon-free construction matters in semiconductor fabs or clean rooms where outgassing can contaminate optics or wafers.
The 5SL4110-6CC carries the typical SENTRON compliance suite: CE marking for the European low-voltage directive, and the 10 kA rating per EN 60898 is the standard for UK/IEC distribution boards. For a mobile repair tech or a quality-doc controller, the nameplate and declaration of conformity cover the essentials — no separate UL or CSA listing is claimed in the evidence, so for North American projects verify local acceptance.
